PHOTOGRAPHTG-PBIN'IZN ft- Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed January 9, 1908. Serial No. 410,032.

To aiifwiwm it mag concern: I a

a citizen of the United States, residing at Whiting, in the county of Addison'and State of Vermont, haveinvented certain new and useful Improvements in Photographic-Printing Machines, of which the following is a specification.

This invention relates to photographic printing machines and is. particularly adapted for printing post cards, and has for an object to provide a machine of this character which may be manufactured at a relatively low figure. j

A further object of this invention is to provide a simple means for alternately printing and releasing the card, i

A further object of this invention is to provide a machine of this character which may be conveniently set up at windows or like places for receiving lignt rays, and thus re- 7 duce the cost of printing to a minimum.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention. v

In the drawings forming a portion of this specification, and in'which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view of the present invention, Fig. 2 1s arear elevational view.

Referrin now more particularly to the drawings, t mm is shown a printing machine 10 comprising vertically disposed spaoedend members 11 and 12 res ectively, a connecting top member 13 and a side member 14. The side member 14 is extended downwardly to a point about midway of the members 11 and 12.

Located beneath the member 14 adjacent one side, there is shown a sliding drawer 15, for a pur ose to be hereinafter described. The mem er 14 is provided with an openingifi.

coated above the opening 16 there is shown a clam ing plate 17 having a downwardly exten ing leg 18 arranged to lie at one side of the opening 16. The plate 17 is adjustable toward and away from the member 14 by means of adjusting bolts 19, as shown. The piate 17 is thus arranged for clamping engagement with a photographic negative as illustrated at 20, and this piate is arranged over the opening 16, as shown.

Located beneath the opening 16, there is shown a trans versely extending rock-shaft 21 journaled in brackets 22 carried by the plate 14. The rock-shaft'is provided with an inwardly curved finger 23, and this finger at its inner end is provided with a presscr block 24 arranged for engagement against the negative 20 at times. One side of this block 24 is arranged to he adjacent the leg 18 depending from the piste 17. The other side of the block 24 is arranged to lie adjacent an elongated block 25 which has a portion 26 engaged with the shaft 21, A leaf-spring 26 is carried by the member 14, and this spring is arranged to bear at one end against a portion of the block 25.

Located outwardly of the leg 18, the shaft 21 is provided with an arm 27 disposed with a portion above the shaft, and is thus arranged to lie with its upper end engaging the member 14. The purpose of this arm will be hereinafter referred to.

The rock-shaft 21 at one end is provided with an arm 28,7located at one side of the member 11,-and at the outer end this arm is connected by a coil s ring 29 and is thus arranged to lie normal y in a downward position whereby the presser block 24 is normally engaged with the negative.

- Upon the opposite side of the plate 17 the member 14 is'provided with a shutter 30 slidable in guides 32 as shown. The shutter 30 is connected by means of a bolt 33 to a rocking arm 34 pivoted as shown at35 to the member 14. The bolt 33 is slidable in a slot 36 formed in the arm 34, as shown. The member 14 is provided with a tortuous slot 37 disposed with a portion beneath the 9 arm 27. The arm 34 is provided with a slot 38, and this slot is arranged to receive a portion of a bolt 39. The bolt 39 is also arranged with a ortion in the slot 37, and outwardly of the s ot 37 the bolt is provided with a cam nut 40.

The bolt 39 is arranged to receive the upper end of a rod 41, and this rod is provided at its lower end with a pedal 42. It will thus be seen that an action of the pedal downward operates the rock arm 34 whereby the shutter 30 is moved away from the opening 16 and the negative 20 is thus exposed to the light. After the shutter 30 has been closed again, the cam shaped nut will slide upwardly The construction is such that paper may be 7,

conveniently fed to the negative. When it is desired to insert a new negative the bolt 19 is loosened and the plate 17 is thus disengaged from the negative whereby the same may be conveniently removed. If desired the spring 29 may be disengaged from the arm 28 whereupon the presser block 24 and other operating parts of the shaft 21 will fall downwardly and out of the away A machine as herein set forth is such as may be conveniently hooded to a window,

or it may be mentioned that a lantern may ibehprovided for producing the necessary What is claimed is:

1. In a photogra hic printing machine, the combination wit a housing having an o ening in one of its walls, of photographic p ate holding means located outwardly of said opening, a rock shaft, a plate engaging block. carried by said rock shaft a vertically movable member, a sliding closure forsaid opening, and means operable by the vertically movable member for alternately controlling said closure and said plate engaging block respectively. I

2. The combination with a printing machine including a housing having an opening in one of its walls, and photogra hic late holding mpans Ilocated lfiiutwlard y o the oen' ,o a oto a 'c ateenain bl ock disposed at oni sihe of said opin ing f a shutter disposed at the other side of said prising a housing having an opening in oneof its walls, a shutter for said 0 ening, photographic plate holding means ocated adjacent said opening, a pivoted member carried by said housing, connections between said pivoted member and said shutter respectively a vertically -movable rod slid- .ably engaged with said ivoted member, a rock shaft carried by sai housing, a photogra ,hic plate engaging block carried by said sha t and means carried by said vertically movable rod for operating said rock shaft.

4. A photographic printing machine comprising a housin nhaving an opening in one of its walls, p otographic plate holding means located outwardly of said opemng, a sliding shutter located inwardly of said opening, a rock shaft, a plate engagin block carried by said rock shaft, means or holdin said plate engaging block yieldingly engage with a late, a fixed arm carried by said rock sha t, a ivoted member carried by said housing and s idably enga ed with said shutter, a bolt slidably engage with said pivoted member, a cam carried by said bolt for 00- engagement with said fixed arm for movement of said plate engaging block, and an operating rodcarried by said bolt.

In testimony whereof I affix my signature, in presence of two witnesses.
